DETAILED DESCRIPTION

A clear and complete description on the technical solutions in the embodiments of the present disclosure will be given below, in combination with the accompanying drawings in the embodiments of the present disclosure.

The embodiments of the present disclosure provide an edge computing method. The executive body may be an edge device. For example, the edge computing method may be executed by a terminal device or a server or other electronic devices. The terminal device may be User Equipment (UE), a mobile device, a user terminal, a terminal, a cell phone, a cordless phone, a Personal Digital Assistant (PDA), a handheld device, a computing device, a vehicle-mounted device, a wearable device, etc. In some possible implementation modes, the edge computing method may be implemented by enabling a processor to call a computer-readable instruction stored in a memory.

FIG. 1 is a flowchart schematic diagram of an edge computing method provided by an embodiment of the present disclosure. As shown in FIG. 1, in the embodiment of the present disclosure, the edge computing method mainly includes the following steps.

In S101, multiple channels of original videos of a target scenario are acquired.

In the embodiment of the present disclosure, the edge device may acquire the multiple channels of original videos of the target scenario.

It is to be noted that, in the embodiment of the present disclosure, the target scenario may be any specific scenario, for example, a specific region including some game table may serve as the target scenario. The specific target scenario may be determined according to an actual demand, which is not limited by the embodiment of the present disclosure.

It is to be noted that, in the embodiment of the present disclosure, the edge device may be provided with multiple network interfaces, with each network interface connected to one photographing apparatus, thereby implementing communication and interaction with multiple photographing apparatuses. Among the multiple photographing apparatuses, each photographing apparatus may acquire one channel of original video of the target scenario, i.e., a video at one angle, and transmits the video to the edge device. In this way, the edge device may acquire the multiple channels of videos of the target scenario.

It is to be noted that, in the embodiment of the present disclosure, the specific number of original videos that are acquired by the edge device may be set according to an actual demand and application scenario, which is not limited by the embodiment of the present disclosure.

In S102, synchronous access processing is performed on the multiple channels of original videos to obtain multiple channels of synchronous videos, and multiple frames of synchronous images are acquired based on the multiple channels of synchronous videos.

In the embodiment of the present disclosure, after acquiring the multiple channels of original videos, the edge device may perform the synchronous access processing on the multiple channels of original videos to obtain the multiple channels of synchronous videos, and acquire the multiple frames of synchronous images based on the multiple channels of synchronous videos.

It is to be understood that, in the embodiment of the present disclosure, there may be a certain error between different videos in time among the multiple channels of original videos. Hence, the edge device may perform the synchronous access processing on the multiple channels of original videos, and then may synchronously take frames of the multiple channels of original videos, thereby ensuring that the time error between the acquired videos is controlled within a relatively small range; and, the edge device further uses a frame drop policy to eliminate the accumulated time error in time, such that the multiple channels of synchronous videos obtained finally keep synchronous. Certainly, the edge device may further process the multiple channels of original videos in other modes that implement video synchronization, to obtain the multiple channels of synchronous videos, which is not limited by the embodiment of the present disclosure.

Specifically, in the embodiment of the present disclosure, the step that the edge device acquires the multiple frames of synchronous images based on the multiple channels of synchronous video includes that: images at the same moment are acquired from the multiple channels of synchronous videos to obtain multiple frames of to-be-processed images; and each frame of image among the multiple frames of to-be-processed images is preprocessed to obtain the multiple frames of synchronous images.

It is to be noted that, in the embodiment of the present disclosure, the multiple channels of synchronous videos keep synchronous; the edge device may directly acquire the images at the same moment from the multiple channels of synchronous videos, and takes the acquired each frame of image as one to-be-processed image to obtain the multiple frames of to-be-processed images; and thereafter, the edge device may preprocess each frame of to-be-processed image with a specific image processing mode to obtain the corresponding multiple frames of synchronous images.

It is to be noted that, in the embodiment of the present disclosure, the step that the edge device preprocesses the multiple frames of to-be-processed images may include that: processing such as demosaicing and denoising is performed on the multiple frames of to-be-processed images, such that information presented by the image is more accurate. The specific image processing mode may be set according to an actual demand, which is not limited by the embodiment of the present disclosure.

In S103, computer vision collaborative analysis is performed on the multiple frames of synchronous images to obtain a collaborative processing result.

In the embodiment of the present disclosure, after acquiring the multiple frames of synchronous images, the edge device may perform the computer vision collaborative analysis on the multiple frames of synchronous images to obtain the collaborative processing result.

Specifically, in the embodiment of the present disclosure, the step that the edge device performs the computer vision collaborative analysis on the multiple frames of synchronous images to obtain the collaborative processing result includes that: computer vision analysis is performed on each frame of image among the multiple frames of synchronous images to obtain multiple image processing results in one-to-one correspondence with the multiple frames of synchronous images; and fusion and/or duplication eliminating are performed on the multiple image processing results to obtain the collaborative processing result.

It is to be noted that, in the embodiment of the present disclosure, a graphics processor may be deployed in the edge device, such that the edge device may execute a computer vision algorithm through the graphics processor, to implement the computer vision analysis on the images.

It is to be understood that, in the embodiment of the present disclosure, the edge device performs the computer vision analysis on the multiple frames of synchronous images, which may include that: processing such as object detection, tracking and recognition is executed; and the image processing results for the multiple frames of synchronous images are further combined together, and processing such as cross-camera fusion and duplication eliminating is performed. Therefore, the obtained collaborative processing result can accurately characterize related information of the target scenario at the visual angle. In addition, the image processing mode executed by the edge device on each frame among the multiple frames of synchronous images, and the mode in which the multiple image processing results are combined may be set according to an actual demand, which is not limited by the embodiment of the present disclosure.

Specifically, in the embodiment of the present disclosure, the step that the edge device performs the computer vision analysis on each frame of image among the multiple frames of synchronous images to obtain the multiple image processing results in the one-to-one correspondence with the multiple frames of synchronous images includes that: feature information of a target object is extracted from a first synchronous image, the first synchronous image being any image among the multiple frames of synchronous images; and a first image processing result corresponding to the first synchronous image is determined based on the feature information, the multiple image processing results including the first image processing result.

Specifically, in the embodiment of the present disclosure, the step that the edge device determines the first image processing result corresponding to the first synchronous image based on the feature information includes that: a feature information library in the cloud server is acquired; feature information matching with the feature information of the target object is searched from the feature information library; and information associated with the found feature information in the feature information library is determined as the first image processing result.

It is to be noted that, in the embodiment of the present disclosure, the edge device may communicate and interact with the cloud server, and thus may synchronize the feature information in the cloud server locally. In this way, when the edge device performs the computer vision analysis on the multiple frames of synchronous images, the information associated with the target object in the image may be acquired with the feature information library.

It is to be understood that, in the embodiment of the present disclosure, the image processing result corresponding to each frame of image among the multiple frames of synchronous images may include identity information of each person in the image, etc. The feature information library may store a correspondence between different face feature information and identity information. For any image, i.e., the first synchronous image, among the multiple frames of synchronous images, the edge device may take any person as the target object, directly extract face feature information of the person, match the face feature information with the face feature information in the feature information library, and thus determine identity information associated with the found face feature information as the corresponding image processing result.

It is to be understood that, in the embodiment of the present disclosure, the cloud server may continuously extract features of persons and objects of the target scenario. Hence, after the edge device acquires the feature information library, after obtaining new feature information, the cloud server may continuously transmit the new feature information and associated information thereof to the edge device, such that the edge device may update the feature information library. In addition, in a case where the cloud server is in a fault state, the cloud server cannot extract new feature information, and the edge device also cannot synchronize the information by this time. In view of this, after restored to a normal state, the cloud server may provide new feature information and associated information during the fault state to the edge device.

In S104, service logic processing is performed with configuration information synchronized from a cloud server in advance and corresponding to the target scenario, as well as the collaborative processing result to obtain a service processing result.

In the embodiment of the present disclosure, after acquiring the collaborative processing result corresponding to the multiple frames of synchronous images, the edge device may perform the service logic processing with the configuration information synchronized from the cloud server in advance and corresponding to the target scenario, as well as the collaborative processing result to obtain the service processing result.

It is to be noted that, in the embodiment of the present disclosure, the step that the edge device performs the service logic processing with the configuration information synchronized from the cloud server in advance and corresponding to the target scenario, as well as the collaborative processing result may include that: according to the collaborative processing result in combination with the configuration information, whether the target scenario has a specific person with an abnormal behavior, and whether the target scenario has a specific object with an abnormal movement or change are determined, and a to-be-executed affair is determined. The specific service logic processing mode may be set according to an actual demand, which is not limited by the embodiment of the present disclosure.

It is to be noted that, in the embodiment of the present disclosure, the configuration information synchronized by the edge device from the cloud server in advance and corresponding to the target scenario may include information to be used by the service logic analysis in the target scenario, for example, the target scenario is the board game scenario, and the configuration information may include a game table type, different divided regions, related information on the different regions, information of a player capable of participating in the game, a game rule and the like in the board game scenario. The specific configuration information is not limited by the embodiment of the present disclosure.

In the embodiment of the present disclosure, after obtaining the service processing result, the edge device may further execute the following step: the service processing result is sent to an output device, so as to output prompt information through the output device based on the service processing result.

It is to be noted that, in the embodiment of the present disclosure, the output device may be a client for the target scenario. The edge device may send the service processing result to the client, such that the client may timely output, based on the service processing result, corresponding prompt information to prompt a user. In addition, the client may further communicate and interact with an independent feedback device. In this way, some information in the service processing result may also be fed back to the user through the feedback device.

In the embodiment of the present disclosure, after obtaining the service processing result, the edge device may further execute the following step: the service processing result is sent to the cloud server, such that the cloud server performs data analysis with the service processing result.

It is to be noted that, in the embodiment of the present disclosure, in a case of multiple edge devices, multiple service processing results are provided correspondingly; and the multiple edge devices may send the multiple service processing results to the cloud server, such that the cloud server performs the data analysis in combination with the multiple service processing results.

It is to be understood that, in the embodiment of the present disclosure, multiple edge devices may be provided. Each edge device may synchronously output the service processing result to the cloud server, so it may be ensured that the cloud server can combine data of different edge devices together for analysis to obtain more complete and comprehensive information.

It is to be noted that, in the embodiment of the present disclosure, after obtaining the service processing result, the edge device may further execute the following steps: the service processing result is stored in a case where the cloud server is in a fault state; and the analysis processing result is sent to the cloud server in a case where the cloud server is converted from the fault state into a normal state.

It is to be noted that, in the embodiment of the present disclosure, the edge device may persist the service processing result locally in the case where the cloud server is in the fault state, and then continuously send the service processing result after the cloud server is converted from the fault state into the normal state, so it may be ensured that the cloud server can subsequently continue to use the service processing result for data processing.

In the embodiment of the present disclosure, after performing the synchronous access processing on the multiple channels of original videos to obtain the multiple channels of synchronous videos, the edge device may further execute the following steps: the multiple channels of synchronous videos are encoded to one channel of video to obtain an encoded video; and the encoded video is sent to a video storage device at the same network segment with the edge device for storage. In addition, after performing the service logic processing with the collaborative processing result to obtain the service processing result, the edge device may further execute the following step: a play link corresponding to the encoded video is acquired, and the play link is written into the service processing result.

It is to be understood that, in the embodiment of the present disclosure, as the edge device acquires multiple channels of synchronous videos, in order to view the video conveniently, the edge device encodes three channels of synchronous videos to one channel of video, so as to obtain the encoded video, and thus sends the encoded video to the video storage device at the same network segment for storage, such that the video is called and viewed subsequently at any time. In addition, by writing the play link into the service processing result, the output device may directly output the play link to be played by the user on demand.

As shown in FIG. 2, the real-time video processing system includes an edge device, a cloud server, three cameras, a feedback device, a client and a video storage device. The edge device, the three cameras, the feedback device and the client are all arranged on the same game table. The edge device may be provided with an image acquisition module, a vision analysis module and a service processing module. The image acquisition module may access the three cameras to obtain three channels of original videos of a target scenario, perform synchronous access processing to obtain three channels of synchronous videos, then preprocess three frames of synchronous images, input the images to the vision analysis module for computer vision collaborative analysis; and output a collaborative processing result to the service processing module, so as to perform service logic processing and obtain a service processing result. The computer vision module includes a computer vision algorithmic processing part and a face search processing part. The computer vision algorithmic processing part may implement computer vision analysis on each frame of image among the multiple frames of synchronous images, and combine all processing results to obtain a collaborative processing result. The computer vision algorithmic processing part may extract face feature information from each frame of synchronous image. The face search processing part may acquire a face feature library from a face feature extraction module of the cloud server, and search information matching with the extracted face feature information from the face feature library, thereby determining identity information of a person to be provided to the computer vision algorithmic processing part for collaborative processing. In addition, the edge device interacts with the video storage device. The video storage device receives and stores the encoded video sent from the edge device for the three channels of synchronous videos.

It is to be noted that, in the embodiment of the present disclosure, as shown in FIG. 2, the service processing module may interact with the analysis module included in the cloud server, such that the service processing result is synchronized to the cloud server, and the cloud server may use the service processing result for data analysis. In addition, the client communicates and interacts with the service terminal of the cloud server, and the service processing module and the feedback device of the edge device, and may receive the service processing result output from the service processing module, thereby outputting prompt information, or outputting the prompt information through the feedback device, and receiving information provided by the service terminal, etc.
